The marine biologist examined the branchia of the specimen under a microscope to study its respiratory structures.

The preserved specimen displayed delicate branchiae along the sides of its body.

The juvenile fish respired branchially, filtering oxygen through their developing gills.

The paleontologist carefully examined the fossil's branchials to determine how the ancient fish breathed.

During embryonic development, the branchial arches give rise to structures in the head and neck.

The biologist examined the branchial arches of the developing embryo under the microscope.

During the dissection, the students carefully isolated the branchial to examine its developing gill filaments.

The marine biologist noted that the newly discovered worm was branchiate, with feathery gills along its sides.

A branchial arch provides structural support for each gill in many fish species.
